No. 12,550 Patented March 20, 1855.

To all whom it may con cm.

TBe it known that IyELBRIDGE HARRIS, of Boston, inthe county ofSuflolkand Com-- monwealth of Massachusetts, have made a facture ofLamps which the injury to clothing, furniture,jand. the danger to per- Iampsare prevented and I doherebyideclare the following {to.bejafulhclear, and

exact description ofthesalne, reference beinghadto the. annexeddrawings, making part ofthis specification, in which- I t Figural is aview of my improved lamp.

Fig. 2 is a section through the same. Fig. 3. yis the" metallicreservoir detached from the H glass body; Fig. 4, anljornamented paper 1covering ofthe reservoir.

The nature of my lnvention consists in i asusuallymade receptaclesformed of sheet offwhatever.kind, so thatany accidental or intentionalfracture ofthe glass part of the lamp, will not cause thefluid contentsto be spilled or inflamed.

1 Toenableothers skilled in the art to apply and use y improvement Iwillproceed to describe it more fully. i X a lhe glass part of thelampA, is-to be blown, or pressed into the desired form as usual, exceptingthatlthe bodyof the lamp drinking glass. I Into the hollow space thecylindricalpr hollow :part of. a metal resercap C,which serves to attachthe whole to the glass partof the lamp. Thus formed the lampxpresents ametallic reservoir, contained [withinthe glass body of the lamp, whilethe top of thelamp is ofpolished or ornamented metal. Inthe common formof left open and the metalreservoirj fitting the body of the lamp ispassed upward. and secured to the cap. Themetal reservoirhas urningfluid, protectors are added, seen at F;Fig.2. I "Several modes ofsecuring the reservoir within the glass receptacle have been adopted; inonethe curved edgeof the metal top projecting over the sidesof the metalreservoir,admits ofa slightly ovalprojection a, Fig. 2, on the glass toenter, when by turning it'the edge ofjjthe capcatches, in notches newand useful Improvement in the Manusons arising from th elfracture ofglass.

introducingwithin the body of glass lamps metal, for containing thecombustible fluids is left open at the top, or bottom, like a;

b whichhave been'cut in the glassabove the shoulder. on which the caprests; another mode allows the edge of the top of the reservoir to beburnished over a projecting bead formed on the glass, in which casethereservoir] is firmly fixed. ,I also make the externalpart of the lampwholly of glass, having'amolded glass top to embrace the burner andcover the reservoir, its edge being cemented to the body.

As the metal reservoir may be made of "burnished, or engraved metalsurfaces, plated, gilded, or lacquered the lamps have an-ex'ternallyrich appearance and require very little cleaning when in use.

To meet the want of low priced lamps of this construction, I have.devised a further improvement: of using ornamented paper, for coveringthat part of the reservoir which is within the glass, such paper asiscovered with polished or embossed metal of different colors ispreferred.In this case the lower part of the reservoir is of ordinary tin plate,or zinc, and the paper is made to surround it, or caused to adhere byits ornamented surface to the interior of the glass. When the glass partof the lamp is plain, the figured metallic surface of the paper producesthe effect of richly engraved metal, and when the lamp'is of pressed orcut glass the plain paper has the rich appearance offpolished gold orsilver.

Lamps furnished with metal reservoirs, when to beused for consuming theheavier oils, such as whale and lard oils, offer the great advantage ofconducting the heat from the wick to the half fluid oil, the glassprotecting the metal from radiation. But

my improvements have special claimsin re lation to security fromaccidents in the consumption of highly inflammable mixtures of alcoholand hydrocarbons. The metal reservoirs cannot be crushed or broken byfilling.

What I claim as my invention and desire to secure by Letters Patent, is-

1. Using within glass lamps of any form reservoirs of metal, which areprovided with the usual tubes. for burning common oils or adapted bymeans of protectors to burn any fluid combustible.

2. I also claim the mode of ornamenting such reservoirs contained withinglass by means of paper with. metal or ornamented surfaces.
